531405 divided by 53 
The aim is to understand the frequency of 53 in 531405.

Step 1:
53 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 53

Going ahead to step 2:
53 can be fit into 53 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 53 from 53, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 53

Step 3:
If we divide 1 by 53, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 53

On to step 4:
If we divide 14 by 53, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 100.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 53

Going ahead to step 5:
The number 53 fits into 140 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 1002.0
Deduct 106 from 140 and we're left with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 53

Let's proceed to step 6:
When dividing 345 by 53, we get 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 10026.0
If we subtract 318 from 345, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
270 divided by 53 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10026.5
Deduct 265 from 270 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
53 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10026.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 53, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 10026.509
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
230 divided by 53 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 10026.5094
If we subtract 212 from 230, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
If we divide 180 by 53, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 10026.50943
If we take 159 away from 180, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
When dividing 210 by 53, we get 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 10026.509433
Deduct 159 from 210 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 10026.509433 with a remainder of 5.1e-06.
